Make it cost 2M so you can critmaneuver with it. And make it knockdown enemies who are airborne, like Ashe's skyhook. I'm a fan of this idea too.

Also make it ignore Evasion, but lower the scaling by 10% (so 110% at Rank 5). The SWA of Polearms doesn't reach high enough. And one Evasion proc into Flottement kind of kills any combo.

Maybe give it a self-cast option, which buffs you with a 'Sky Hook stance', any enemies who go airborne on their turn within 2 tiles of you will get knocked down, and take half damage of the normal Skyhigh.
